once the heater system malfunction

light causes the unit efficiency

will lead to the shutdown or equipment damage. Therefore

in the operation process

monitoring system and high effective parameters

can timely judge whether there is high failure

and do a good job of risk prevention

to eliminate high leakage fault in the initial state

the unit economy and safety guarantee and improve greatly

have certain reference significance for similar unit.
